feat: migrate mingling-specific picker code into mingling crate

BREAKING CHANGE: Remove `mingling_support` feature from arg-picker
crate. The
`EntryPicker` trait and `corebind` module are now part of the mingling
crate
directly, and `build_pattern1` is now a public method.

-/// Trait for converting Mingling entry types (types that implement `Groupped<R>` and `Into<Vec<String>>`)
-/// into [`Picker`] instances for a given route type `R`.
-///
-/// This trait provides a bridge between entry definitions created with the `mingling` framework
-/// and the picker argument system used for CLI argument parsing and routing.
-///
-/// # Type Parameters
-///
-/// * `'a` — The lifetime of the picker and its references to argument definitions.
-/// * `This` — The program type used for dispatching runtime routes; must implement [`ProgramCollect`].
-/// * `Route` — The route type used for dispatching; must implement [`Groupped<This>`].
